n this study, various chain lengths of 1' isosorbide (IC 22, IC 32, IC 52, IC 102, IC 29, IC 39, IC 59, IC 89) was prepared from
isosorbide and ethylene oxide or propylene oxide in the presence of K

. The successful synthesis of 1' isosorbide (IC
22, IC 32, IC 52, IC 102, IC 29, IC 39, IC 59, IC 89) was confirmed by
1
H-nuclear magnetic resonance (
1
H-NMR). Bio-based
high elastic polyurethanes were made using polycaprolactone diol, various chain lengths of 1' isosorbide and hexamethylene
diisocyanate. The polyurethanes were produced by one-shot bulk polymerization without catalyst. The successful synthesis
of the polyurethanes was confirmed by FT-IR and GPC. The thermal and mechanical properties were characterized by
thermogravimetric analyzer (TGA), differential scanning calorimetry (DSC). The mechanical properties were measured using
universal testing machine (UTM). Degradation test was performed using PBS solution and biocompatibilities of PUs were
tested using C2C12 for biomedical applications.
